PLANT-11PROTECTOR SPECIFICATION forming part of Letters Eat-,ent No. 705,019, dated July 22, 1902. Appnction inea cantera, 1901. seria No. 77,610. uro moan.)

To all whom t may concern.'

Be it known that I, EDWARD CARs'rEN HENRY BEHRENS, of Charleston, county of Charleston, and State of South Carolina, have invented an Improvement in Plant-Protectors, of which the following is a specification.

This Vinvention relates to `new and useful improvementsv in plant-protecting devices, comprising a `hood to which are connected pivotal arms whereby the hood is suspend ed and means for raising said pivotal arms and automatically holding the same at a given height.

The invention consists, further, in various details of construction and combinations of parts, as will be hereinafter fully described and then specifically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, in which- Figure l is a side elevation of my improved plantprotecting device. Fig. 2 is an end view.

Reference now being had to the details of the drawings by letter, A designates a hood,

which is held in semicylindrical shape by means of metallic ribs B, spaced apart, and to alternate ribs are fastenedthe pivotal arms C, the ends of which arms project beyond the diameter of said hood. Posts D are provided at suitable locations, to each of which is pivoted an arm C by means of a pivotal pin C.

Each post also carries a pulley E, mounted in a suitable bracket E', and also a second pulleyr F, mounted in an aperture in the lower portion of the post. Ropes H each have an end secured to an arm C and pass over a pulley .E and F and are then spliced to the main operating-rope K, which may be secured as shown at the left of Fig. l. Adj ustably held on each post is a locking-plate N; preferably of metal, having an elongated slot N', through which a screw N2 passes. A portion of said plate projects, asat N3, laterally to form a stop for the under edge of the pivotal end of arm C to prevent the said arm being raised above a substantially horizontal position, hence preventing the hood from being lifted higher without first withdrawing said plates out of the path of said arms. Riveted or otherwise secured to the lower portion of each lockingplate N is a bracket-plate Q, and R designates flanged collars secured to the main op= erating-rope, the iianges of which are adapted to strike against the rear portions of said plates Q as the main operating-rope is drawn toward the post L, and as said flanges come in contact with the plates and the rope isfurther pulled the plates N will -be thrown toward the post L and the projecting portions N3 will be thrown out of the pathof the rear ends of the arms C and the latter will be ali lowed to rise above a horizontal position,

which will cause the hood to lbe lifted from the ground; A pin P is fastened to each post D and provided for the purpose of forming a stop to prevent arm C from falling be low a horizontal position.'

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A plant-protecting device comprising a hood, a series of posts, pivotal arms mounted,

one on each post and each fastened to thev hood, a rope fastened to the end of each arm and passing about suitable pulleys, locking means, and means for automatically operat= ing the same, as set forth.

2. A plant-protecting device comprising a hood, aseries of posts, an arm pivoted to each post and fastened to the hood, a rope passing about suitablepulleys on the postand connect ed at one end to said arm, a pivoted locking-V plate mounted on each post, and having a projecting portion on one edge thereof, and means for throwing saidplates out of the path of the rear ends of said arms,as set forth.

3. A plant=protecting device comprising a hood, posts, a pivotal arm carried by each post and fastened to the hood, a rope fastened to the outer end, ofleach arm and passing about plleys'on the post, an adjustable plate pivotally mounted on each post and having a' projecting portion adapted to forma stop to prevent the arm being thrown above a horizontal position, and means for throwing said plates out of the path of the rear ends of the arms as the ropes are drawn upon, as set forth.

4. A plantprotecting device comprising a hood, a series of ribs spaced apart, posts, an arm pivoted to each post, a rope fastened at one end to the said arm and passing about ICG pulleys on the post, a plate pvoted to each so that projecting portions thereof will be out post, a main operating-rope secured to each of the path of the pivotal ends of the arms, as of said ropes which pass about said pulleys, set forth.

collars on said main operating-rope, bracket- EDWARD CARSTEN HENRY BEHRENS. 5 plates secured to the locking-plates, and Witnesses:
